Timer
A Timer function enables two timed periods to be set in a 24 hour period. The Timer is used in conjunction
with the Standard Heating Mode to control the times of operation of the heat pump. Refer to
page 21.
Vacation Mode
Vacation Mode enables energy to be conserved during a set period, such as when away on holidays. The heat
pump and electric heating unit are prevented from operating under standard heating conditions. Refer to
on page 24.
Locking the Display Panel
The Display Panel can be locked to prevent unauthorised or accidental adjustments being made. Refer to
on page 27.
Fault Codes
In the event the water heater develops a fault, a code will display in the Main Display Area This function of the
water heater indicates to the user a service call is required. Refer to
on page 27.
Manual Electric Heating Mode
The water heater has a Manual Electric Heating Mode which allows the electric heating unit to be manually
switched on to heat the water. This would be used in the event the heat pump develops a fault which prevents
the heat pump from operating and heating the water. This mode can be used to provide hot water prior to a
service call being made to correct the fault. Refer to
“Manual Electric Heating Mode”
on page 27.
DISPLAY WHEN ELECTRICITY SUPPLY IS TURNED ON AT THE ISOLATING SWITCH
Note:
When the electrical supply is switched on, there will be a knocking sound coming from the heat pump
for a short period of time. This is the electronic expansion valve operating. This is normal and not a fault with
the heat pump.
When the electricity supply is switched on to the water heater at the water heater isolating switch:
•
All icons on the display panel illuminate blue. After two (2) seconds the Selection Key icons illuminate red
for a further for two (2) seconds. Then all icons on the Display Panel go out.
•
After a short initialisation period where a combination of icons illuminate;
◼
‘OFF’ is displayed in the Main Display Area and the Display icons of previously set functions illuminate
blue in the upper part of the Display Panel, and
◼
Selection Key icons of previously set functions illuminate red, and
◼
Selection Key icons not in use illuminate blue in the lower part of the Display Panel.
•
During this short period, inputs from pressing the Selection Keys are ignored by the water heater.
The water heater has a memory function. When the electricity supply is switched on to the water heater after
having been switched off, or if electricity is reinstated to the water heater after a time controlled electricity
supply period, previous settings including the time remain stored. The water heater and heat pump will return
to the programmed state at the time the electricity supply being interrupted.
It is necessary to turn the heat pump “On” at the Display Panel after the electricity supply is switched on to the
water heater at the water heater isolating switch for the first time.
The heat pump must be “On” at the Display
Panel for the heat pump to operate and heat the water.
Note:
After one (1) minute of Display Panel inactivity, the illuminated Display and Selection Key icons go out
and the Display Panel becomes blank.
